Application led February 5, 1912. Serial No. 675,501.

1'0 UU Yui/0m 1' t may concern: Beit Lnown that I, HANS Rmssn'r, a subf ject of the Emperor of Germany, residing at Cologne, Germany, have invented certain new and useful Improvementf in Apparatus for which the following is a specification.

This invention relates to means whereby constant quantities' of water per u nit of time may be delivered from pipe-systems with fluctuating water-pressure, filters Ain which there is a progressive clogging and opposition to the flow of liquid, or from tanks or reservoirs with water levels of varying or decreasing heights.

The object of the invention is to provide a novel apparatus o1 this character, .which will be eicientin operation and have the greatest simplicity of construction consistf ent with the objects to be attained.

A particular object o f the in'vention is to control a variably-openmg valveor passage so as to automatically compensate for vary,-v

mg pressures by means of a float which is placed in a by-pass around the valve.

Another particular object of the inven` tion is to control the flow of water by means of a variably'opc'ningvalve or passage which is operated by an open float, which is filled more. or less with liquid according .to the variations in pressure.

A further object is to so construct the apparatus for controlling thc rate of flow that it enables the source ol' supply or pipesvstenrto be completely drained, and is itseli' self-draining.

A. iurther object is to provide manuallyoperated means whereby the apparatus may be completely closed ually opened thereby.

'.lhe invention consists inthe parts, improvements and combinations hereinafter described and illustrated in connection with the preferred embodiments thereof and more particularly pointed out in the appended claims.

ln the. acconipanying drawings ,illustrating the invention: Figure 1 isay vertical section through one. form of apparatus; and Fig. 2 is a similar view of another form of :lpparatus .I v.

Numerous other embodiments of the invention may be devised. l

The. means for controlling the -flow= of water or other liquid is preferably em- Controlling the Flow of Lquids, of

but may not be manhousing, 'affording 'reservoir or pipe-system. -1s/sim1larly adapted to beconnected with ,a delivery or distrlbutlng bodied in a self-contained apparatus, which may be Vinstalled in connection with any' filter, tank o r other system; but it will be obvious that the parts may be constructed and arranged vin other'ways. l

The' two illustrated forms of controlling device'will now be described brieiy.

In Fig. 1, 10 indicates a suitable for'ml of.

a passage,v orV a section of a passage, through which the W'ater to be delivered must How. This musing is' shown as containing two chambers l1 and 12, the 'former-being at -the up-streanr-,or source side of the valve 13, and. the other at the down-stream side thereof. The cham'-l ber 11 has a suitable flange-whereby it may be secured to the outlet from a filter, tank,

pipe or system or receiving receptacle. The chamber' 12 is provided with any suitable form of conf trollable device, such as a gate valve for throttling'the outflow therefrom. This device may be set for vany desired rate of delivery. It is indicated diagrammatically at 23. 'Fhevalve 13 may be of any suit-able form, but preferably comprises two cones mounted on a. vertical stem 14. these cones cooperating with openings 15 in horizontal walls sepan-ating the two chambers. The' lower end of the stein 14 is shown as received in a suitable guide 1 0, and the upper part of tlu stem is shown as passing loosely through a guide 17 inserted in the top wall of the chamber 11. 18 is a float-container,

.The chamber 1 2 the same being preferably mounted upon and over the housing 10. lVithin the floatcontainer is a float 19; and connections are' provided whereby-.this float operates the, valve 13. While any suitable form .of connections maybe employed, I prefer to se cure the valve stem 14. to the ioat, the arrangement shown being such that rising of the float opens or increases the opening of the valve=controlled passages. and the descent of the float diminishes the opcningor closes the'same. In accordance with the preferred form ofthe intention` the fioat is located in a by-pass around the'valve. In`- the `particulai-construction illustrated this,"

is efi'ccted by. providing communication be-"fb tween theQchamber 11 'at the. source si'de of the valve andthe interior of-the fioat'feon#4 tainer 18, and by making the float open,

with inlets from the Hoet-container and a communication with the chamber 12 at the down-stream side of the va'lve. The inlet from the chamber 11 to the float' container 18 is afforded by the annular space between the stem 14 and the guide .17. The inlet communication from the float-container to the' interior of the float 19 is afforded yby means of one or more Weep-openings Q0 disposed at a certain height in the float, above the dischar v'e of the' inletv 21 to' the float; container. g.he stem 14. is hollow, and communicates at its upper end with the interior of the float, and at its lower end with the chamber 12, by means of one or more small openings 22.- The total area of the Weepopenings' 20 isv preferably equal to or greater than the area. of the' inlet 21 tothe float-container, and the openings 22 :ma preferably of a combined areal egual to or greater than the area of the openmg 21.

In operation', assuming that the {loabconi tainer 18 is empty, the fioat down and the valve 13 closed, water enters the chamber 11 and is forced upward through the inlet 21 into the float-container 18, where it rises and lifts the float, so as to open the valve.

Water now flows into the chamber 12. 'and' by virtue of the throttlihg at 23 and the resulting back-pressure enters 1the holesiQZ and rises upward through the stem 14- into i the interior f the fioat,'thereby Weighting the latter. he water in the float-container enters the float through the weep-o enings 20. An equilibrium is now establie ed for the pressures obtaini a't the time, water from the 11p-stream si e of the valve entering the neat-container and thence passin through the Wee -holcs'into the interior o the float, from w ich it escapes more or less rapidly according to' the ann uit of back'- pressure in the chamber 12. The valve is thus held at a certain degree of opening, permitting the water to flow past the same at the desired rate. The water in the iloatcontainer 18 remains approximately at the level of the weep-openings. A decrease in pressure at the down-stream side of the valve, resulting from a decrease of pressure or head at the up-stream orV source side thereof, enables morewater to iow out of the interior of the fiofat, while at-the same time the flow of water through the weepholes 2O into the float is somewhat diminished; the resu'lt being that the fioat rises sufficiently to increase the o enin of the' valve to an extent where' the e'sire outilow from the device is a ain secured and equilibrium is restablis ed. A11 increase in pressure has the reverse results. The .water column' from the 'central line between the valve'openngs 15 tothe level of the water in the nteriorof thel float, remains approximately constant, y

` The form of apparatus shown in Fig. 2,

is similar to the preceding, and features common to both and bearing similar reference characters will not agaln be described. In this form of e invention l. provide means Afortra. ping a suiicient quantity of Water in the mat-container 18^t0 keep the -fioat at such height that the valve 13 rclnains open when the last quantities of water are being' drained from the source of supply, and the pressure in the chamber 11 has therefore fallen so low that it would no longer preserve a d th of Water. in the container. l

-als'd 'provi e' means for automatically drain ing the regulating apparatus.` In this form of the invention, also, I show manual means for closing the vulve and theby-pass so that the apparatus may be absolutely closed, this means being incapable of operation to o en the valve. I shall now describe briefly t e referred construction illustrated, but

it will beunderstood that numerous other embodiments may be devised. The vfioat 19* is'annulfar in cross-section. l't has inside' of it concentric tubular walls and 31. '0f these the, inner wall 30 is joined ina Watertight manner to the bottom of the float 19, .around the central o enimz therein. The outer wall 31 is secure :toa head or block 32 carried by the fioat, and `depends into the water s ace therein, with its lower end somewhat a ove the bottom thereof.V so that-an vinlet to the annular space 33 between the walls 30 and 31 is afforded in the lower part of the ioat. The hollow stem or conduit 14* extends upward for a sufficient heightto be secured to a plate 34 connecting it with the wall 30. A chamber 35 is formed between .the head 32 and this'plate 34, and places the upper end of` the' stem 14"` in communication with the upper end of the annular space 33.

In this way, a siphonconnection is aiforded between the interior of the ioat and the chamber 12, so that all the water in the float will be. suol-red out when the source of supply is being drained. From around the passage 21 a tube 36 extends upward between the stem 1/1 and the' Wall 30;' so that annular spaces are aii'orded be tween the tube 36 andthe stein, on the one hand and between the tube and .'.he wall 30 on tlie other. The water entbring the float-container must first pass up through the inner annular space and then down through the outer one. In this hay, a Siphon connection would be established between the chamber 11 and the interior of the'oat-containen In order that, when the pressure in the chamber 11 falls very low owing to the draining of' the source of supply, the water V'n'ay not be sucked out of the float-container so as to cause the valve' 18' to close before draining of the sdurceof supply is completed,-I provide an air-admission opening or vopenings to the crown of this Siphon. These openings are prefer` las 'sullicient to hold the float up with the valve open, the float having been emptied by suction in the `manner already described.

Means are provided l,for closing the air-- admission openings in the bolts 37 to the siphon inlet of the Haat-container. This means is preferably embodied in a disk 38 having a packing face adapted to be pressed down over the tops of these openings. This disk may be operated manually by means of a' screw 39 passing through a cover 40,

which closes the float-container so as to prevent access to the interior thereof. In the preferred construction, the member 38 also serves to close the bypass to force the doub le valve 13 against its seats. Closing of the valve is accomplished by virtue of the fact that depression of the float forces the stem. letl downward thus pressing the two cones against their seats. Closing of the bypass is preferably effected by closing the inlet from the chamber 11 tothe floatcontainer. To this end l provide a2 packingring 4l around the `base of. the tube 3C, whichus contacted by the bottom of the float when the latter is depressed by the member 38, so that the space between the tube 36 and the wall 30 is cut off from the interior of the float-container. In addition to this, the air-admission openings in the bolts 37 are closed. Thus, the whole apparatus is completely closed, so that water can neither pass the valve, nor enter the float-container, nor escape through the openings in the hollow bolts 37 Since upward movement of the member 38 by means of the screw 39 merely Separates this member from the loat, it follows that the inember and screw constitute an embodiment of manual means whereby the valve may be closed, but may not be opened. The operation of this form ot the invention is, in essential. aspects. simila r to that of the pre- -ceding construction.
